This invention relates to certain improve;

ments in rail bonds, and particularl-yto an improvedmeans forsecuringthe bond wire to the rail.

vThe particular "object of the present i-n.-.j

vent-ion is to overcome the'variousdisadvantages and inherent defects ofthe present typesof rail bonds in generaluse. Accord.

ing to the old method of makin a rail bond, or the one in most generause, a tapered channel pin carrying'the bond w re in the channel wasdriven into an opening in the rail, and usually in the web of the rail.Thiswas found-tobe objectionable, owing. to water getting into thejoint, cansing oxidation and a choking of the current,

' and it was for the. purpose ofeliminating these very undesirableconditions that the construction constituting my present invention hasbeen devised. v I. p f

- Generally stated, theinvention comprises a metal plate for attachmentto the r'ail,

formed with an upturned edge providing a loop in which one end of thebond wire is leaving a portion of the ferrule projecting through saidplate, after which the projecting portion of the ferrule is swaged orturned over the notched flange of theplate to force the shoulder of theferrule in close contact with the inner side of the flange of the plate,and to also cause the swaged-over portion of the ferrule to be pressedinto interlocking engagement with the notched edge of said flange, thusforming an interlocking connection between the ferrule and the plate andpreventing any relative movement of the parts. After the plate andferrule have been thus assembled, the rear projecting end of the ferruleis inserted into an opening in the rail and looked therein by a taperedpin which is driven into the ferrule.

The preferred embodiment Or the M..-

tion is illustrated in the accompanying drawings, in which Fig.1 isaiside elevation of half-section of a rail joint having the inventionapplied" thereto.

Fig. 2 is an sembled relation. Fig. 3 is a side elevation of the bracketwith the bond wire attached'thereto.'

Fig-4 is a front elevation oft-he plate. Fig. ois a vertical sectionthereof, and Fig. 6is a side e'levationofthe ferrule.

. Referring to the drawings l represents an end portion of arail ajacenta rail joint to which the invention is adapted to be applied,.and 2, asection of the fishplate associated therewith. The rail bond wire 3 isadapted to span the joint'in the 'customary mannerand its intermediateportion is supported by one or more clips 4, preferably secured to thefish plate 2, as shown enlarged end View, partly'in section,illustrating the various arts inns For the: sake of convenience inillust'rat-io'n and description, only a half-jointis shown;

but it' is ofcourse to be understood/that both ends of the 'bo'ndwire 3are secured to the adjoining rail sections in {a similar manner. This isaccomplished by af-novel form of bracket comprising a plate 5 of sheetsteel or other suitable metal having a lower upturned loop 6 in whichthe end of I the bond wire is secured. The upper intermediate portion ofthe plate 0 is provided with an opening 7 having a struck-up flange 8,the outer edge of said flange being pro- 7 vided with one or morenotches 9. Adapted to be secured within the opening? of the plate 5 is asoft metal ferrule 10, preferably of copper, having formed adjacent oneend thereof a tapered annular shoulder 11, which shoulder, when theferrule 10 is inserted in the opening 7 of the plate 5,

will engage the inner tapered or inclined surface of the struck-upflange 8.

To firmly secure the ferrule 10 invthis position to the plate 5, thatportion of the ferrule projecting through the opening 7 is swaged orturned back over the notched flan e 8 to force the annular shoulder 11of the ferrule in close contact with the inner-inclined surface of theflange 8 and the swaged over portion of the ferrule into in tel-lockingengagement with the notches 9 of said flange 8, this interlockingconneclit) tion between the ferrule 10 and the plate 5 preventing anyrelative movement between the parts.

After these parts have been thus assembled, the projecting portion ofthe ferrule is inserted in an opening formedpreferably in the web of therail and secured therein by a driven tapered pin 12, which will forcethe soft metal of the ferrule into the grain of the metal of the railand thereby provide a water-tight connection between said bracket andrail.

With the above arrangement and construction a triple-locked device isproduced. The shoulder 11 formedon the ferrule first engages the plateon one side, the turned over end of the ferrule engages the plate on theopposite side, and the tapered pin, in addition to securing the bracketto the rail, also acts as an additional means for lockingthe variousparts together. It is tobenoted also that aside from assisting insecuring the ferrule 10 to the plate 5, the shoulder 11 performs anotherfunction. When it is desired to remove the bracket from the rail, thelock pin12 is driven out, and as the ferrule 10 is forcedoutward theshoulder 11 will cause the bracket plate. 5 tocmove outwardly with itWithout imposing any strain on the bracket, the said parts beingmaintained in their interlocked relation.

WVhat I claim is 1. A rail bond, comprising a two-part bracket includinga plate having ,a wireengaging loop at one edge, said plate also havingan opening and an annular flange surrounding said opening formed with aninner tapered face, a ferrule mounted in said opening having an annularshoulder with an inner tapered face, a ferrule mounts; ed 1n saidopening having an annular sho11lder ad acent one end, thereof engag ngthe inner tapered, face of the annular flangev on the plate, an outerendturned backover said notched flange and a projecting inner end adaptedto be inserted in anopening in a rail, and a tapered pin for wedging Q73. A rail bond connector, comprising a plate havlng an opening thereinsurroundedthe ferrule in the latter opening.

by a flange provided with a notched rim, and a wire receiving loopat oneedge. of said plate; a ferrule mounted in said opening having an annularflange engaging the plate at the peripheraledge of said opening, anouter end turned back overtsaid flange and interlocking with the notchededge of the latter, and an inner end adapted to engage an opening in arail; and means for we'dging the ferrule in the latter openlng.
